Summary
Microtubule organization is well-studied in cell cultures, but in vivo dynamics in differentiated cells are less understood. Recent advances reveal conserved yet diverse mechanisms for microtubule remodeling in vivo.
Area of Science:
- Cell Biology
- Cytoskeleton Dynamics
Background:
- Extensive research has elucidated microtubule organization and dynamics in vitro.
- Understanding of microtubule behavior in vivo, within differentiated cells and tissues, remains limited.
Purpose of the Study:
- To review recent advances in studying microtubule dynamics in vivo.
- To highlight the diversity of molecular mechanisms governing microtubule reorganization in differentiated cells.
Main Methods:
- Utilizing new genetic tools for in situ probing of microtubules.
- Leveraging advanced imaging technologies for in vivo studies.
- Analyzing microtubule dynamics in differentiated cells and tissues.
Main Results:
- Differentiated cells employ conserved strategies for microtubule remodeling.
- Significant diversity exists in the molecular mechanisms underlying microtubule reorganization.
- In vivo studies reveal context-specific regulation of microtubule geometry.
Conclusions:
- Despite conserved strategies, molecular mechanisms for microtubule reorganization vary considerably across differentiated cells in vivo.
- Further investigation is crucial to understand how differentiated cells regulate microtubule geometry in vivo.

2.6K
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.

Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.

Microtubules are the thickest cytoskeletal filaments with a diameter of 25 nm. In prokaryotic organisms, microtubules are commonly found in locomotory appendages like cilia and flagella. In eukaryotic cells, microtubules form specialized extensions for moving fluid over the surface, like those found in cells lining the intestine.
Microtubules have two structurally similar globular protein subunits: α and β tubulins. In the cytosol, the α and β tubulins form a heterodimer....

Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...

7.8K
Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation...
